It is a rational because it can be expressed as the quotient of two integers
Rational numbers are, by definition, expressible that way.
The quotient of two nonzero integers is the definition of a rational number. There are nonzero numbers other than integers (imaginary, rational non-integers) that the quotient of would not be a rational number. If the two nonzero numbers are rational themselves, then the quotient will be rational. (For example, 4 divided by 2 is 2: all of those numbers are rational).
A rational number is one such that it is "capable of being expressed as an integer or a quotient of integers, excluding zero as a denominator." So you must ask yourself: can 2.25 be expressed as a quotient of integers? In other words, can you divide one integer by another and get 2.25? The answer is yes, because 9 divided by 4 is 2.25. Therefore, 2.25 is a rational number.
It is a rational number; that is, a quotient of two integers. In its simplest form the denominator has at least one factor other than 2 and 5.
